MUSICAL BEER HELMET

This is the musical beer helmet! its a very simple project!

all you need is an arduino nano, a 9v battery, either a speaker or a jack cable and a pressure sensor.

To make this all i did was connect the pressure sensor to the arduino with 4 wires (as it says in the how to here https://learn.adafruit.com/adafruit-mprls-ported-pressure-sensor-breakout)

these connections are :-\

SCL PIN to the arduino nanos A5

SDA PIN to the arduino nanos A4

VIN PIN to the 5v pin on the arduino nano

GND pin to GND on the arduino nano

then attach your 9v battery pack RED WIRE to VIN on arduino nano, and BLACK WIRE to GND on arduino nano

then wire either a speaker or a jack socket to pin D9 on arduino nano, and the -ve to GND on the arduino nano

YOUR DONE. now go to the adafruit link above, and download and install the sensor library for the code to work

then install this code :-

basically the way this synth works is you blow into it, and the air gets split down to the two cans, one end the air is just expelled, and the other side it goes directly to the pressure sensor, this means when your blowing it feels like a natural instrument instead of just being blocked.
